Mailbox Forwarding Records (MBOXFW)

PowerDNS no longer supports MBOXFW records natively. However, JPoweradmin supports MBOXFW records by utilizing an EXIM MTA configured for the purpose of forwarding emails. The EXIM MTA acts as the Mail Exchange (MX) system for zones than utilize MBOXFW records.


  1. Adjust exim4.conf file (found in the resources directory) to suit your installation
  2. Create an MX record pointing to your EXIM MTA for each zone that requires MBOXFW support
  3. Create MBOXFW records
